Former Alabama AG sues Facebook

{} {} Former Alabama Attorney General Troy King's law firm is going after Facebook. {}The firm King & Nix and Morgan & Morgan is filing a class action suit on behalf of people who bought Facebook stock.

{} {} The lawsuit claims a registration statement for the company's initial public offering was misleading. {}It also says Facebook did not inform potential investors that it anticipated a drop in revenue.

{} {} That drop is because of more people accessing the social networking service through mobile devices. {}In that type of access, users don't see as many ads as they would see in a web browser.
